Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X125-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X125-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 125mm stroke, 1/4" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X125-10S
With a 50 mm bore this MACJ50X125-10S develops 981 N of push at 0.5 MPa, a force class that suits clamp-and-hold fixtures and medium press work. The extend stroke can be trimmed on site within a 10 mm window by the external adjuster, and a variable air cushion at both ends soaks up end-of-travel shock so the covers survive fast 30-800 mm/s cycling.
The round body is a riveted stainless-steel barrel with a hard-chrome plated carbon-steel rod, a build that shrugs off washdown mist where painted minis swell and rust. A magnet is built into the piston as standard, so CMSG / DMSG / EMSG switches clamp straight on. At 0.5 MPa, plan on roughly 589 N of practical working force, which lifts about 50 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X125-10S Is Used
Bottle capper thrust pad
A 10 mm trim lets the capper head stop exactly at cap seating on 250 ml sauce bottles, with the 981 N push at 0.5 MPa driving a smooth, repeatable press.
Pusher on a cookie line
Cushioned ends let the pusher run at 500 mm/s without jarring baked goods off the belt, and the stainless barrel tolerates daily washdown.
Fixture clamp on a drilling jig
Clamps aluminium brackets repeatably; the built-in magnet feeds a CMSG switch so the drill only starts once the clamp is proven.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X125-10S the Right Cylinder?
If 981 N at 0.5 MPa is more than the job needs, the MACJ40 delivers 628 N for tighter spaces; when the load creeps higher, step up to the MACJ63 at 1558 N. The adjuster is a mechanical end stop only - with air lost the rod still drifts, so add a locking valve when the load must stay put. FA flange or LB foot mounting, I and Y rod knuckles, 1/4 inch ports, PT / G / NPT threads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X125-10S FAQ
Double-acting with a 10 mm adjustable extend window and variable cushion at both ends. At 0.5 MPa it pushes 981.3 N and pulls 880.8 N; at 0.7 MPa push rises to 1373.8 N, and the theoretical maximum is 200.1 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, ports 1/4 inch, rod 16 mm.
Yes - every MACJ ships with the piston magnet as standard, so CMSG, DMSG and EMSG switches snap into the barrel groove without a special-order piston or retrofit.
